Parallel to 5G, when will the 6G era arrive?

Parallel to 5G, when will the 6G era arrive? The second "Global 6G Technology Conference" held from March 22nd to March 24th showed the world the process of global 6G development and also asked: When will the 6G era come in parallel with 5G? The second "Global 6G Technology Conference" was held from March 22nd to March 24th to show the world the progress of the global 6G development. In fact, China has been following the principle of "use one generation, research one generation and reserve one generation" in communication technology. As early as the end of 2019, the Ministry of Science and Technology led the establishment of the 6G technology research and development promotion working group and the overall expert group, China's 6G technology research and development work has been officially launched. The European Union announced in December last year the allocation of 240 million euros to launch the first large-scale 6G research and innovation program; South Korea announced last June that it would invest 220 billion won to develop and standardize 6G core technologies by 2025; Japan has also formed a government-private alliance and plans to submit a draft 6G international standard to an international conference in June this year; the U.S. Telecom Industry Association has set up "6G Alliance", the coordination of industry technology giants to promote the United States in the next communications development cycle (10 years), to achieve 6G and even 7G field of global leadership. So, what is the difference between 6G, which countries have laid out, and 5G, which we are using now? The most obvious difference between the two may be in the network speed, 6G network band is terahertz band, 5G network is millimeter wave band. It is understood that the propagation speed of 6G network will be 100 times faster than 5G, which can reach almost 1TB per second. Such a network speed is expected to reduce the time delay and promote the development of technologies such as unmanned vehicles and drones. Industrial Internet may become the research focus of 6G When it comes to the research focus of 6G, Wu Hequan, academician of the Chinese Academy of Engineering and chairman of the Future Mobile Communications Forum, believes that the research focus of 6G should be the industrial Internet. 5G era, "5G + edge computing" fusion applications significantly reduce enterprise operating costs, improve production efficiency, optimize the allocation of manufacturing resources, improve product high-end, equipment high-end and production intelligence. The 5G+edge computing convergence application can significantly reduce the operation cost of enterprises, improve the production efficiency, optimize the allocation of manufacturing resources, enhance the high-end products, high-end equipment and intelligent production level, promote the manufacturing industry to achieve quality and efficiency improvement, industrial structure optimization, development mode transformation and growth momentum transformation, and provide a strong guarantee for industrial Internet. However, 5G lacks 2B application focused research, and the high frequency and large bandwidth of 6G makes it possible to build base stations in workshops. AI applications focus on energy efficiency optimization and intelligent adaptation Unlike the 5G era where AI is mainly used for operation and maintenance management, 6G will focus on energy efficiency optimization and intelligent adaptation. 6G technology will reshape the way people interact with AI, build rich application models, call and load AI algorithms in different scenarios, and improve AI models at the same time. Development of 6G does not mean the immediate disappearance of 5G Many people have such doubts because 4G replaced 3G. according to the historical experience, wireless communication technology is upgraded by one generation almost every ten years, and researchers believe that 6G technology will be commercially available in about 2030. But in reality, even if operators begin to deploy 6G networks in 2030, there must be a process of 4G/5G/6G coexistence. In this process, 6G will be parallel to 5G for a while. 4G replaces 3G and people enter the era of short video. In the long run, 6G is a historical necessity to replace 5G, but in terms of the current progress, the three major application scenarios of 5G have not yet all landed. 6G seems to be seen as an expansion of 5G, and even though its propagation speed is fast, the lag of supporting hardware technologies such as XR and sensors is also preventing it from replacing 5G. industry insiders expect 5G to have a long life cycle, and the communications industry, IoT, and the government are all actively contributing to 5G. government are also actively contributing to the implementation of 5G applications. In addition, operators have not yet recovered the large amount of capital invested in 5G, so there is no way to build next-generation communications facilities on a large scale, and it makes sense that 6G and 5G will run in parallel. Augmented reality demonstration, restaurant digital menu, everything smart ...... Imagine that your cell phone will be able to identify the terminal devices around you, acting as a bridge between the physical world and the digital world. And these, perhaps, will happen at the moment when the 6G era really arrives.
